> Legal & Logical

After having failed his exam in "Logistics and Organization", a
student goes and confronts his lecturer about it.

Student: "Sir, do you really understand anything about the subject?"

Professor: "Surely I must. Otherwise I would not be a professor!"

Student: "Great, well then I would like to ask you a question.

If you can give me the correct answer, I will accept my mark as is
and go. If you however do not know the answer, I want you give me an
"A" for the exam. "

Professor: "Okay, it's a deal. So what is the question?"

Student: "What is legal, but not logical, logical, but not legal, and
neither logical, nor legal?"

Even after some long and hard consideration, the professor cannot
give the student an answer, and therefore changes his exam mark into
an "A", as agreed.

Afterwards, the professor calls on his best student and asks him the
same question.

He immediately answers: "Sir, you are 63 years old and married to a
35 year old woman, which is legal, but not logical. Your wife has a
25 year old lover, which is logical, but not legal. The fact that you
have given your wife's lover an "A", although he really should have
failed, is neither legal, nor logical."
